This process consists in filling a mould 1 with a slurry of cellular concrete, and then in removing from the mould the panel formed after the slurry has hardened, this panel then being baked. The process according to the invention is characterised in that it comprises a stage which consists in applying pressure to the upper face of the said slurry, whilst it is in the plastic state inside the mould 1, in order to form a compressed surface on the said concrete panel. PROCEDE DE FABRICATION D'UN PANNEAU LEGER EN BETON CELLULAIRE.CE PROCEDE CONSISTE A REMPLIR UN MOULE 1 D'UN COULIS DE BETON CELLULAIRE PUIS A DEMOULER LE PANNEAU FORME APRES DURCISSEMENT DU COULIS, CE PANNEAU ETANT ALORS SOUMIS A UN TRAITEMENT DE CUISSON.LE PROCEDE SELON L'INVENTION SE CARACTERISE PAR LE FAIT QU'IL COMPORTE UNE ETAPE QUI CONSISTE A APPUYER SUR LA SURFACE SUPERIEURE DUDIT COULIS, ALORS QU'IL EST A L'ETAT PLASTIQUE DANS LE MOULE 1 AFIN DE FORMER UNE SURFACE COMPRIMEE SUR LEDIT PANNEAU DE BETON.
